Right, that's another one (initial report was throwing on CurvedRowChild, this is on CurvedComposableChild).
I'll take a look.

Fix bug for a CurvedLayout changing children on a SideEffect.

Previously, the internal "curved tree" was updated in the main
dereivedStateOf on CurvedLayout when a container changed it's content.
This may cause it to be out of sync with compose's tree.
Now, we update our tree during composition, so they are kept sync.
